PROBLEM TO BE SOLVED : To provide a solid electrolyte fuel cell capable of maintaining a stable output performance in a long period by improving junction strength between an air electrode and a solid electrolyte. SOLUTION : This is a solid electrolyte fuel cell wherein a solid electrolyte 31 and a fuel electrode 33 made of stabilized or partially stabilized ZrO2 containing a rare earth element are successively formed on the external surface of a cylindrical air electrode 32 comprising a perovskite type compound oxide containing at least La, Ca, a rare earth element, and Mn. And in the solid electrolyte 31 the peak A of the quantity of the rare earth element is formed at a prescribed depth along the peripheral surface of the air electrode 32 of the solid electrolyte 31.
